IMPROVEMENTJN LAMPS- Speeifioation forming part of Letters Patent No. ISL 109., dated February 13, 1877; application filed December 6, 1876.

To all whom it may concern Be it known that I, STEPHEN S. NEWTON, of Binghamton, in the county of Broome and in the State of New York, have invented certain new and useful Improvements in Lamps; and hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

Figure 1 is a perspective view, partly in section, of one part of my invention. Fig. 2 shows a modification of the filling-tube. Fig. 3 represents another part of the invention.

The object of the first part of my invention is to provide a convenient, safe, and expellitious method of filling a kerosene-oil lamp without removing the burner; and to this end this part of the invention consists in combining, with the burner, a filling-tube, provided at its inner end with numerous ports, or a wire-gauze strainer, which will permit a free passage of oil, but will prevent the ignition of the oil or gas within the lamp, should flame be communicatedto the oil or vapor within the filling-tube.

The invention further consists of certain details of construction, which will be fully, explained. In Fig. 1, G G is the filling-tube, the inner end having several perforations, g". The outer end of the tube has a port, g and is surrounded by a sleeve, G which is provided with a corresponding port or opening, 9. g is a spring friction-stop, secured to the tube, with its free end resting upon the sleeve G. g is a gas-escape tube, connecting at its lower end with the perforated end of the filling-tube, its upper open end passing up by the side of the wick-tube.

It will, of course, be understood that the end Gr of the filling-tube extends out beyond the burner to a distance convenient for filling, and itwill be readily seen that after the oil has been poured in through port g this port can be closed by rotating the sleeve G and that the sleeve will be held in place by the spring friction-stop g.

In Fig. 2, I have shown the shaft G on which the star-wheels F F are mounted, made hollow, with one end enlarged, and provided with a rotating sleeve, (3, and ports g 9 through which to pour oil, the inner port f opening into a tube provided at its lower end with perforations, substantially as shown at g", Fig. l, and in substantially the same position relative to the wick-tube.

By turning the tubular shaft G around until ports 9 are up, the shaft may be used as a filling-tube, as is tube G G In Fig. 3 the filling-tube is represented by A A. E is the wick-tube, and E is a dripcup, or drip-collar, to collect the oil, which would otherwise flow down the wick-tube to the upper plate of the burner, located at about the line :10 x, and would pass from there down the outside of the lamp. e is a small tube, serving to conduct oil from the drip-cup E to the body of the lamp through the filling-tube,

and also as a gas-escape.

In Figs. 1, 2, and 3, I have left out such parts of the burner as are not needed to illustrate my invention.

1 do not claim, broadly, the employment of a filling-tube projecting from the lamp and having a strainer, but my construction possesses some advantages over those heretofore used. By arranging it horizontally I am enabled to employ it to actuate the starwheels, and by using an external rotating sleeve to close the filling-port I am enabled to use a tube of small diameter where it passes through the collar, and of large size where the oil is poured in, which is desirable in a horizontal tube.

Having thus described my invention, what I olaimis- I 1. In a lamp a horizontally-projecting filling-tube, provided with an enlarged outer end, and also provided at its inner end with numerous ports to prevent the ignition of gas through the filling-tube, substantially as set forth.

2. In a lamp the combination, with the projectingfilling-tube, provided with an enlarged outer end, of a sleeve rotating on the outside of said tube, which serves to close the oilopening in the tubes, substantially as set forth.

3. In a lamp, the combination of a projecting filling-tube, the sleeve G and spring friction-stop, g, substantially as set forth.

4. In a lamp, the combination of the ga shereunto set my band this 15th day of Novemescape tube g,' with the filling-tube G Gr, sl bhep, 1,875." stantially as set forth.

5. The combination of the wick-tube E, the drip-cup E, drip-tube e, and the filling-tube Witnesses:
